add bbox support to goesaodc_createTibble

[jonathancallahan]

Most satellite data use cases for the USFS AirFire group involve looking at a region of interest -- typically the size of a state or smaller.

We can make everything work faster and use much less memory if we only ingest data within the area of interest. To do this, the goesaodc_createTibble() function needs to support a bbox argument. The function signature should look like this:

goesaodc_createTibbl <- function(
  nc = NULL,
  bbox = NULL
) {
  ...
}

Prototype code demonstrating how to convert a bbox into curvilinear coordinate bounding indices and then ingest only the data within those bounding indices is found on the jon branch in local_jon/Kincade-20191027-example.R.

Done.
